Is there any benefit to using a higher gauge wire going from the battery to the alternator and power distribution fuse box. Or is 1/0 gauge wire only benefical for sound systems.

It'll get more voltage to your higher drain devices. But other than that there's no real benefit.

it will help out current flow alot... but using 1/0 under the hood to upgrade the big three is kinda overkill, unless you have a huge(and i mean HUGE) stereo. 4ga oughta do the trick just fine.

Lowes or home depot have the perfect solution. Wire that is thick as hell, with a heavy duty insulation. it is less conductors though, where car stereo power wire has thousands of conductors, this wire will have less than 100 thick conductors.

you dont wanna do that man... go to your local car stereo shop, look at the big wire and see how flexible it is, then go to the hardware store and try flexing it. it will be a bia to run that wire in your car, in a house it is a different story.

you can go that route if you want, but trust me, live and learn. there are someways you can save money, and there are some ways you can screw yourself, and sometimes those two comcepts fall under the same category ;)

But i wouldn't need that much wire to run to different components in the engine bay, and i have used it and it is stiff, but it cna be managed especially when heat is applied.

if you want to then go for it. but the end result is going to be a lumpy wire that going to have sharp defined bends(as opposed to a nice smooth flow), and it is going to look like something that should have been hidden behind a sheet of drywall.

but if you want to use it and save a few bucks, go for it.

The best way to look at power wire is this. Try breathing through a straw, then try breathing through a paper towel roll. If you see the benefit for that, then you will see the benefit for bigger wire. Bigger is not always needed, but it can never be too big...(insert dirty joke here____________). Stay away from anything Home Depot or Lowes or any place like that sells for 12 volt wiring. You would think it would be the same thing, but way different, okay...maybe not WAY.

I used #2 THHN building wire to go to the battery in the trunk. In this case though I wanted something fairly rigid.

Go to Del Cityand look at their battery cable. It is fairly cheap and they offer fast service. Matter of fact it is on sale this month.
